to answer the original question...Tanman -
all the Machetes are REAL skis, regardless of what people write. they come from a generation of volants where the construction of the ski had already been changed to deal with the delamination problem (so don't worry about the FB's delamming on you).
secondly, no body in their right mind buys a FB for short turns and bumps. however, every volant i've skied did well in the bumps (relatively, of course, to the width of the ski). this is not a super forgiving ski. it can sit you on your butt quick if you let the ski get ahead of you. the machetes are all super stable. remember - the flex patterns were designed and approved by the craziest of all of us, Shane McConkey. he wanted to call this ski the fat bastard, but someone had already trademarked that name for a spoof movie. no sense of humor.
thirdly, don't mount the binding forward. it will shorten the way the ski turns because you will flex the entire back end of the ski off the snow in hard, short turns. this will result in entire loss of edge control, and then you won't be carving anymore. i mounted a pair of stiff, wide skis (explosivs) forward, and i wish i hadn't. they did ski great backwards that way, though...
if you think you'll need help turning the ski, get a Marker Piston or Glide binding. these bindings have "floating toes" that move the toe forward on the ski as the ski is flexed. the result is more forward pressure to really help initiate and keep a turn happening. i mount the piston version on all my skis, even the super fat ones, and they make a ton of difference in the way the ski skis.
with all this in mind, here's a grain of salt: i ski 180 explosivs and 190 gotamas almost everyday. i'm 5'9", 150 pounds. they both have super long radius sidecuts and i don't care - i make them turn short or just wave to speed control people when i go by them. get em, ski em, you'll love em
fat skis rock. put xc bindings on your old skinny ones.
